On android you can choose whether to grant access to contacts. And most apps work fine without.
GrapheneOS, which I use, also has contact scopes, so troublesome apps that refuse to work without access will think they have full access. You can allow them to see no contacts or a small subset.
There's also multiple user profiles, a "private space", and a work profile (shelter) that you can install an app into, which can be completely isolated from your main profile, so no contacts.
It surprises me how far behind iOS is with this stuff. Recently I wanted to install a second instance of an app on my wife's iPhone so she could use multiple logins simultaneously, there didn't really seem to be a way to do it.
